In recent years, achieving the integration of the four networks and improving the overall transportation efficiency of the rail transit system has become a research hotspot and development direction. From the perspective of the signal system, the key to achieving "four network integration" is to achieve the integration of the CTCS system of the high-speed railway and the CBTC system of the subway. Using the existing mature CTCS system and CBTC system as technologies, research the key technologies of train control system that support the integration of four networks, solve the technical problems of incompatibility between the two systems, achieve interconnection and interoperability, and support safe and efficient cross line operation of trains. This article studies the key technologies of train control systems that support efficient cross line operation of CTCS and CBTC, including onboard equipment, ground equipment, and overlap area design. It also provides a detailed description of the specific process of cross line operation without stopping in automatic driving mode. Cross line operation is achieved through compatibility of on-board equipment with ground equipment, reducing the number of ground equipment, simplifying the system structure, providing system security, reliability, and maintainability, and also having significant cost advantages; Adopting integrated on-board equipment with a simple system structure, low equipment cost, and low requirements for installation space is the main direction of future technological development; The key technologies of the train control system compatible with CTCS and CBTC proposed in this article can be used to guide system design, research and application, and have important guiding significance for achieving "four network integration".
